Abstract

　ノード（２０）は、ユーザ端末（１０）が第１のコンテンツサーバにアクセスするために送信した第１のパケットデータ（２０Ａ）に対するアドレス解決結果（２０Ａ′）と、前記第１のパケットデータ（２０Ａ）の送信元を自ノードとする第２のパケットデータ（２０Ｂ）に対するアドレス解決結果（２０Ｂ′）とを比較し、その比較結果が異なる場合に、第２のアドレス解決結果（２０Ｂ′）をユーザ端末（１０）に割り当てて、ユーザ端末（１０）と第２のアドレス解決結果（２０Ｂ′）が示す第２のコンテンツサーバとの間の通信路を設定する。ユーザ端末（１０）は、前記割り当てられた第２のアドレス解決結果（２０Ｂ′）を用いて前記通信路にて前記第２のコンテンツサーバにアクセスする。
